Justicia kampotiana Benoist (쥐꼬리망초과)를 베트남 미기록종으로 보고한다. 본 종은 유사종인 J. ingrata Benoist와 달리 외화관에 털이있으며, 화통은 판연 보다 약간 길고 화병보다는 아주 짧다. 종 동정을 위한 기재, 그림도해 및 컬러사진과 함께 본 종과 유사종의 비교를 위한 검색형질들을 제시하였다.

Andrographis stenophylla C. B. Clarke., (Acanthaceae) is an erect glabrous undershrub with very narrow leaves and stems from a stout rootstock, the corolla pale with dark red stripes. The plant grows in hills of about 1200 meters height in South India. No scientific work reports are available with regard to this plant. The present study, thus deals with the detailed pharmacognostical evaluation of the plant A. stenophylla using light and confocal microscopy, WHO recommended physico-chemical determinations and authentic phytochemical procedures. The physico-chemical, morphological and histological parameters presented in this paper may be proposed as parameters to establish the authenticity of A. stenophylla and can possibly help to differentiate the drug from its other species.

세인트폴리아(Saintpaulia ionanth)의 잎에는 노랑 또는 갈색의 반점이 많이 생긴다. 이러한 반점은 leaf spot라고 불리며 관수시엽온이 급격히 떨어지는 쇼크(Temperature Drop Shock: TDS)에 기인하는 것으로 알려져 있다. TDS에 의해 발생하는 leaf spot에 대해서는 세인트폴리아 외에는 지금까지 발표된 바 없다. 본 연구에서는 이러한 엽상해가 어떤 종류의 식물에서 발생하는지 알아보기 위해, 세인트폴리아가 속해 있는 Gesneriaceae과 식물을 중심으로 조사하였다. 그 결과, Gesneriaceae과 식물에서는 Gloxinia 등 10속, 26종의 식물에서 leaf spot가 발생하였으며, Acanthaceae과 식물에서는 7속, 8종의 식물에서 발생하였다. Leaf spot이 발생하는 식물들의 잎에서는 어떠한 형태적, 해부학적 유사성이 발견되지 않았다. 어떤 식물의 잎은 두껍고 단단한 반면, 어떤 식물의 잎은 얇고 부드러웠다. 그러나 leaf spot이 발생한 모든 식물들에 있어 TDS에 의한 상해는 책상조직세포에만 발생하였고, 엽록소형광도 TDS 처리 직후 급격히 감소하여 회복되지 않는 등, 세인트폴리아에서의 leaf spot과 동일한 현상을 보였다. 이러한 결과들로부터 TDS에 의해 발생하는 엽상해는 세인트폴리아만이 아니라 좀더 넓은 범위의 식물에서 발생된다는 사실이 명확해졌다.

Chronic oral toxicity studies (90 days) on aqueous and methanol extracts of the whole plant of Peristrophe paniculata (Forssk) Brummitt were carried out in Wistar rats. The dosage was 200 mg/kg/day, p.o. for both the extracts. All external morphological and biochemical changes, in addition to body weight and vital organ weights were recorded. During this investigation, no significant mortality was observed. The results showed that both the extracts were devoid of any toxicity at the dose level studied as compared to the control group.

Arusa (Adhatoda vasica) is an important medicinal plant widely used in Unani system of medicine of (Family-Acanthaceae). The leaves of Adhatoda vasica contain several biologically active phytochemicals such as alkaloids, tannins, saponins, phenolics and flavonoids. It mainly consists of pyrroquinazoline, alkaloids, viz. vasicine, vasicol, vasicinone, peganine along with other minor constituents. The plant possesses diverse pharmacological activities, In Unani system of medicine, the drug is described as having dafa-e-tashannuj (anti-spasmodic), qatil-e-jarasim (antibiotic), mukhrij-e-balgham (expectorant), dafa-e-humma (antipyretic) properties due to which it is prescribed in a wide range of ailments like influenza, tuberculosis, bronchitis, gastric ulcers etc. Leaf juice is beneficial in the treatment of dysentery and diarrhoea. Various other activities like radio modulation, hypoglycaemic effect, cardiovascular protection, antitubercular, antiviral, hepatoprotective and antioxidant activity have also been reported.

The ethanolic (50% v/v) extracts of Peristrophe bicalyculata Nees. (Acanthaceae) were examined for anti-inflammatory and analgesic activities in experimental animals. P. bicalyculata in doses of 50, 100 and 200 mg/kg caused a dose dependent inhibition of swelling caused by carrageenin equivalent to 12.25-24.49% protection and 16.62-39.44% in cotton pellet induced granuloma in rats. There was a significant increase in the tail-flick reaction time in mice (18.05-76.43% protection) and analgesy-meter induced pain in rats (14.49-56.85%) protection). The extract of P. bicalyculata resulted in an inhibition of stretching episodes and the protection range of 14.49-56.85% respectively in acetic acid induced writhing.

Plantlet regeneration in Asteracantha longifolia(L.) Nees (Acanthaceae), a medicinal herb has been achieved from seedling explants on basal MS medium. Three different seedling explants including node, internode and leaf segments on used. Of these three explant, leaf explants gave better response for both callus mediated organogenesis and direct multiple shoot induction. Number of explants showing differentiation of shout buds was higher on MS media supplemented with BA compared to kinetin. MS medium fortified with BA ($2.0mgl^{-1}$) and NAA ($0.5mgl^{-1}$) was found to be most suitable for both callus mediated organogenesis and elongation of shouts. The elongated shoots were successfully routed on MS medium fortified with NAA or IBA. Among them $0.1mgl^{-1}$ NAA or $0.2mgl^{-1}$ IBA provides better response for rhizogenesis. Regenerated plantlets were successfully established in soil where 85.4% or them developed into morphologically normal and fertile plants. RAPD profiling using four decamer primers confirmed the genetic uniformity of the regenerated plantlets and substantiated the efficacy and suitability of this protocol for in vitro propagation of A. longifolia.

Through the collection of herbarium specimens in Bhutan over the years, new plant species are discovered nearly annually. Thus, this paper reports two new genera and 19 new records of flowering plant species from Bhutan. The new genera include Eurycorymbus of the family Sapindaceae and Homalium of the family Salicaceae. The new records of plant species are Eranthemum erythrochilum (Acanthaceae), Hemidesmus indicus (Apocynaceae), Ilex umbellulata (Aquifoliaceae), Canarium strictum (Burseraceae), Ehretia acuminate (Boraginaceae), Vaccinium sikkimense (Ericaceae), Nothapodytes foetida (Icacinaceae), Machilus edulis (Lauraceae), Grewia asiatica (Malvaceae), Hibiscus fragrans (Malvaceae), Cipadessa baccifera (Meliaceae), Baccaurea javanica (Phyllanthaceae), Canthiumera glabra (Rubiaceae), Homalium napaulense (Salicaceae), Eurycorymbus cavaleriei (Sapindaceae), Acmella radicans (Asteraceae), Silene latifolia (Caryophyllaceae), Cleome rutidosperma (Cleomaceae), and Cuphea carthagenensis (Lythraceae). Morphological determinations of the genera and species were carried out at the National Herbarium (THIM) of the National Biodiversity Centre of Bhutan. Brief descriptions of the species, phenology, and photo plates are provided in this annotated checklist.
